My invention relates more particularly to improvements in the, typezottray supporting racks used in. bakerieskitchens ot large hotels andother placeswherea. considerable: quantity. of. pan ro'11s,dcughnuts,buns and other similar types ofv bakery goods are handled.

The principal. objecmofz the present. invention is to provide amimprovedasupporting. rack of the type; described which. possesses. manyadvantages over those heretofore produced: including great.- errloading; capacityease. 0t; accessibility and: ease ofzmovement.

A further object is to provide an improvedtray rackzthah willz havve aplurality of rows of shelves extending outwardly radially from a commonaxis, supported 1151181101). manner that the entire unit may be. movedin, a. circular direction by grasping any shelf and swinging the entireunit about its pivot.

A furtherobjece of the inventiondsto provide a revolving tray rack ofthe. type described; that is. extremely; sturdy. and rigid; yet sufiiciently light so; that: any, ordinary, persomis ablestio=move thesame:ab:out, at,.will..

A. further. object or the invention is to provide a. revolving-:trayrack. construction: of the: typesdescribedi that: canbe easily and:cheaply built and will. not; easily become. broken: or outrof. ordereven whenrsubiectedtorlong and'hard usages.

In the preferred embodiment of the invention which I have chosen toillustrate, in Fig. 1, I have shown. thebase Hawhi hl has a combinedthrust. and; radial; bearingilf provided. axial thereof. to support ;avertically. disposedipostl member IS; The post" member "5' maybenrovidedlwith. col- Iars-IB and that its lower. and. upper ends.resnectivelyli Radiallie directed; angIemembers 22 extend. outwardly.rom. the. lower collar I'B'v and similar-radially extended. angle.members. 24? extend outwardly from. the. uppers collar. 201.

Aslthusgfandescribed, Irhaveprovided a base and. a. rotatable. octagonalframe which. is,.mounted thereon and capable ofrotationuponthecombinedmadialrand thrusthearing. I45

Imonder, however to. support thisframe even unevenly, loaded, aswilLbe'laten explainedl have provideia plurality of; roller members 32: whicharenuniversallyg;mounted.and. fastened. to. the lower. side. of. the:frame. 26. so. that a. portion of the .loadeofthezirame. and thetrayswhichis supports will; be. carried: adjacentthe. sides of. theoctagom.

Tray racks 36, all similar in constructiorn may beformecl of. rodbenttorarurshape .and. fastened to. facing, legs ofitheangle. upright":-membersv 30 spacedgazdistance of approximately: six. inches apart Each.o-.the-legs.may,have.alongitudinal bracez3flyand. a; OBOSSrbIIQCB 4i! sothatllarger. or smaller trayssma'y, be :.p1aced upon.- the. same.

Theracks 42 are similar in construction to the racks 36 and may have theinner ends thereof welded or otherwise secured to upright supportmembers 44 which are secured at both their upper and lower ends to theframe members 26 and 28 by the strap members 48 and 50. The tray racks42 may also be braced with a radial brace 52 and a cross-brace 54 and.be welded or otherwise rigidly secured at their inner ends to theupright angles 44 hereinbefore described.

With the construction thus described, it can be seen that I haveprovided a rotatable multiple tray support which provides in the normalheight which is practical approximately 20 rows of racks, eight to therow, or 160 racks. And this in a space which is comparatively compact sothat anyone of the racks is easily accessible and which has the furtheradvantage of being capable of rotation, so that a person may stand inone position and, by v merely swinging the unit about its pivot, placetrays or remove trays from any of the other rows of racks desired.

Multiple trays racks of the type described are sometimes inserted intoovens loaded with trays of goods to be baked, and frequently themeansfor supporting the same in the oven may consist of an overheadtrolley arrangement. -Accordingly, in Fig. 1a, I have shown a hookmember rotation of the entire unit upon the hook when the hook issupported by an overhead track or similar support.

While I have shown and described the preferred embodiment and onemodification of the invention, it will be understood by those skilled inthe art that changes and modifications may 51 which is rotatablyfastened by a nut '53 to the flange. to which the upper end of the postmember [6' has been connected. With this construction, the entire unitcan be lifted bodily, the base 12 being rotatable upon the post [6, butbeing carried thereby.

' In the modified form of the invention which I have shown in Figs. 3and 4, I have provided a base which includes the four legs 60 thatextend outwardly from a central pivot 62. Each of the'lcgs are providedwith roller casters 64 universally mounted so that the unit may be movedin any desired direction. Upon'the pivot 62 which may include a combinedroller and thrust bearing 66, I have mounted center post 68 which maycarry a pair of horizontal wooden frame members 10 and 72. These framemembers extend sideways and connect to vertical post members 74 and 76.As thus far described, the multiple base 60 may support a rotatableframe which includes the center post 68 mounted in the bearing 66 andwhich carries the rectangular frame consisting of the upper and lowercrossmembers 76 and 72 and the vertical frame members 74 and 16.

The vertical frame members 14 and 16 may have a plurality of tray racks18-and 80 secured thereto extending in opposite directions from thesides thereof. Each of the tray racks may include a bracing structurehaving a longitudinal brace 82 anda cross-brace 84. Certain of the trayracks 78a and 8611 are extended a short distance further than the restso that these may be grasped to swing, the complete unit about on itspivot. Y

For a comparatively high revolving tray rack of this type it issometimes desirable to provide additional bracing to prevent it frombecoming top-heavy, and accordingly I have shown a pair of angle members90 and 92 which extend outwardly from the lower end of the post 68 anddownwardly as shown at 94 and 96. The lower ends of these members areprovided with a universally mounted roller caster 98. With thisconstruction it will be comparatively easy to move the entire unitabout, and any danger of the be' made in the exact details shown, and Ido not wish to be limited in any particular; rather what I desire tosecure and protect by Letters Patent of the United States-is:-

A revolvable trayrack construction including a supporting base, avertical post member rotatably positioned thereon, said post havingcollars at its upper and lower ends respectively, radially directedangle members extending outwardly from said collars, polygonally shapedframes secured to said top and bottom angle members,

upright braces connecting said frames at their corners and medially ofeach side, tray supporting racks secured to each pair of adjacent cornerbraces and a row of tray supporting racks secured to each pair ofadjacent medial upright braces.
